- the validation device is designed such that a residual service life can also be calculated from the determined, in particular total air volume and the corresponding measurement duration of the air conveyor device.
- characteristic values, characteristic curves and empirical values can be stored in a database for each type of fan, so that the remaining service life can be determined at the respective time for the respective fan in use, starting from the determined air volume and the total volume of air that is eligible for this fan, namely, the difference between the volume of air delivered and the average volume of air that can be conveyed over the lifetime.
- the validation device can access customer data in a database of a data center in order to match the detected air volume flow in accordance with a customer-specific value stored in the database assign a billing amount and use it to create an analog or digital bill.
- Customer data in the sense of the present invention are, as it were, data of a specific user, customer or a purchaser of an air volume in one or more installations.
- a transmission device in order to transmit the determined billing value or an invoice based on the billing value to an external interface, for example a customer interface, or a specially defined interface.
- an external interface for example a customer interface, or a specially defined interface.
- the transmission device is designed to transmit the determined residual life to an external interface. In this way, it is not only possible to determine an amount of air already conveyed by the air conveyor, to validate its value and to invoice it to the user via an accounting function, but also to regularly determine the remaining service life of the air conveyor in order to determine the time or to predict when the air conveyor is to be replaced or maintained.
- the measuring device is designed to detect a pressure drop or in particular the differential pressure as ventilation parameters, namely at a measuring position, vorzugswei se at the air passage, for determining the air volume, which is to be brought to the bill.
- a pressure drop or in particular the differential pressure as ventilation parameters, namely at a measuring position, vorzugswei se at the air passage, for determining the air volume, which is to be brought to the bill.
- other digital or analogue measuring devices which are suitable for carrying out such an air conditioning system. see parameters of the volumetric flow, from which the volume of air conveyed can be determined.
- the measuring device is designed to record the air-conditioning parameter or parameters continuously over a desired time period or at least in discrete successive, in particular fixed time intervals.
- a specifically selected ventilation parameter such as the pressure drop
- the evaluation unit has an arithmetic operator, preferably a digital integrator, which is designed to calculate a total volume flow by integration over a specific time period T from the measured time-sequential air-technical parameters. It is advantageously provided that the period of time is freely scalable and selectable in order to be able to coordinate and define accounting periods with the user in this way.
- the evaluation has a microcontroller to accomplish in this way with standardized Con troller processes the evaluation task.
- the transmission device is designed to transmit the data wirelessly or by wire via a network topology, preferably via a conventional network topology.
- a further aspect of the present invention relates to a method for detecting and accounting for a volume flow generated by an air conveyor, preferably with an air quantity detection and billing device, as described above. This method comprises the following steps:
- the remaining service life of the air conveyor is also determined by the evaluation unit in the air volume determined in steps b) and c) and via an especially external interface is transmitted to a receiving unit suitable for receiving the data.
- FIG. 1 is a schematic system structure of an embodiment of the present invention
- Fig. 2 shows an alternative embodiment of the invention similar to the imple mentation of FIGS. 1 and
- Fig. 3 is a schematic view of a fan in a system according to Figures 1 and 2.
- a Luftmengener Errors- and accounting device 1 each comprising an air conveyor 10, a measuring device 20, an evaluation device 30, a transmission device 40 and a va lid ists driven 50th
- the air conveying device 10 is, for example, a ventilator and serves to generate a specific volume flow through the air passage 11, which is likewise shown. This is intended to simplify an application-related installation situation in which a user has a certain volume of air through a defined volume flow through the air passage 11 (as in FIG FIG. 3) should be made available.
- the measuring device 20 shown only by way of example is designed to measure at least one ventilation parameter P of the respective air volume flow Q, which passes through the air passage 11.
- the air-technical parameter P selected for this purpose is one which, in each case in connection with the air volume flow Q, enables a direct calculation possibility of the air volume passing through the air passage 11 over a time period T.
- the evaluation unit 30 is designed to evaluate the measured Pa parameters P, in order to determine the total volume of air that has been promoted over a period of time T through the air passage 11 of the air conveyor 10.
- the measurement of the pressure drop Mes be used on an annular nozzle at the air passage 11.
- the pressure drop measured in this way can be converted into a volume flow with a correction factor.
- K represents a factor that takes into account the specific nozzle characteristics of the annular nozzle.
- APw represents the differential pressure of the static pressures.
- Q determines the volume flow. It is advantageous if the pressure decrease takes place at, for example, four points on the circumference of the inlet nozzle E.
